The chamber of secrets escapes from the mirror of candy heaven and reflects on the crystal in the following specific ways:

Tools/raw materials

Demonstration computer: ultramicro X8DAL main server chassis

Computer operating system: Windows 10 Professional Edition 64-bit operating system.

1. Wipe the dust off the lens with a rag. Take off the lens of your glasses and use it to reflect the sunshine outside. At this time, all four mirrors are illuminated by refracted light, as shown in the figure.

2. The light refracts into the embossed disc in the middle, and the stone door opens. This is an optical channel game, as shown in the figure. Just refract the light to the bottom exit according to the specified path as required.

3. Complete the light refraction game, open the door of the round slate and get the red longan, as shown in the figure. Put it on the relief of the right door to open the door of the outer courtyard of the Dragon Palace.

4. Open the first guard door and enter the yard. There are two doors in the Dragon Palace. You need to move the wooden latch and open the second door again to enter the Dragon Palace passage.
